Glass decoration element have been known for centuries. Many of them are preserved in a good shape. Actually, glass production development was started from many tiny glass beads. Some of these products belong to very important historical objects which undergoing conservator activity to preserve our cultural heritage. To realise such enterprise very detailed research should be done. This paper is about the testing of different glass decoration elements which belong to historical objects, in order to get information about their history and technology production. This research was carried out on small pieces of glass borrowed from historical objects in partnership between AGH - Technical University of Science and Technology and four different conservator groups. Testing made use of non-destructive techniques, like: EDS, FTIR, AFM.
